Applicationfiled July 14, 1906. Serial No. 326.174.

T all whom, it may concern:

Be it known that'I, BENJAMIN F. MERRITT, a citizen of the United States, and a resident of East Orange, county of Essex, State of New Jersey, .have'invented certain new and useful Im rovements in Telephone-Booths, of which the following is a specification.

, My invention relates to booths or inclosed stalls in which telephone instruments are located, so that communication may be held in privacy.

The object of my invention is to improve the means for supporting and operating the door in such a booth.

I'providea booth 01. inclosure having a floor and a ceiling. The door-opening extends substantially from the floor to the ceiling. There are guiding-groovesin the-floor.

' and ceiling, and pins on the top andbottom a nut and. a set-nut.

- door.

edges of the door run in these grooves. There is a pivoted radial arm above the ceiling.

Its free end is bent back or returned, so that the terminal is U-shaped. A wheel or anti- 'friction device is pivoted at the junction of the two le s of the U-shaped terminal. 1 The armj'and t e return section of the terminal are erlip'rated to receive a threaded bolt. On t is oIt between the legs of the U there is Theother end of the bolt is fixed to a strap, and the strap is fixed to the door at itstop edge at a point mter'me di ate the vertical edges.

receive the bolt, steadies the bolt and the The bolt is separable from the radial arm, and the door can be adjusted as regards its height by changinglthe position of the nut.

The accompanying drawings illustrate' my.

invention.

.Fi ure 1 is "a sectional frontview of the boot with the door open. Fig. 2 is a sectional view showing the floor and lower portion ofthe booth. Fig. 3 is a section'showing a plan of the ceiling. Figs. 4and 5 are views of the pivoted radial arm, and Figs. 6 and 7 are views of the device for .armwith the door:

a is a booth with a ceiling b, a floor c, a seat is, a telephone-table t,- and a door (1. This door swings in a horizontal plane and is controlled by grooves 10 in the floor 0 and 11 in or near the ceiling. A pin 12 in the bottom 7 of the door betweenits vertical edges engages The Wheel travels on the top of the ceiling, and the radial arm, with its terminal returned, as described, to

connecting the i l i floor on the other edge. '(see Fig. 5) in the return member 16- of the arm 14 is smaller-than the perforation 18 perforation at 17 and a perforation-M18.-

On the free end of the arm 14 is pivoted a wheel 20. This wheel travels on the top of the ceiling and supports the door (2. he

door d is connected to thearm 14 by means of a bolt 30, having a screw-thread with a washer 31, a nut 32, and a set-nut 33. The

lower end of the bolt 30 is made integral with a strap or "plate of iron 40, suitably perforated and attached to the door (I by means of screws at a point in its u er edge intermediate the vertical edges. e bolt 30 is passed through" ,the perforations 18 and 17 in the arm 14, and the nut 32 is. laced in position between the legs of the U s aped terminal of the arm 14. a

By. changing bolt the position of the door (1 may be regulated or adjusted, and the form and arrangement given the arm 14 enables the single bolt 30'tohold the door d steady in the required operative position.

the position of the nut on the Washer 31, Figs. 6 and 7, is designed to increase the. surface contact with the radial arm '14 and to prevent any relative movement between the nut 32 and the radial arm 1'4 fromexerting a tendency to unscrewthe nut-i132.

Theradial arm 14, with its U-shaped terminal, provides a long bearing for the bolt 30 and holds the door in a vertical position vents the, bolt 30 from bindingin the arc-- 'shapedgroove or passage in the ceiling. The

washer 31', the nut 32, and the set-nut 33 provide means for varying the height of thei'rom the ceiling on one edge and from the The perforation 17 door orvarying thespace separating the door a i the arm 14. This is shown inFig'. 3, where. j

the two holes are represented as concentric.

What I claim, an desire to secure by Letters Patent, is-

booth having a roof or covering, a ccil-.

, ing having its free end turned back to form a eling on the upper side of said ceiling and a g ing separated afixed distancefrom said roof', 1 mechanical connection between the upper and a suitable floor in combination with a l edge of said door and the free end of said arm door swinging and moving in a horizontal consisting of a threaded bolt extending plane, guiding-grooves in the ceiling and in through the U-shaped terminal of the arm, the floor, projections in the upper and lower means for fixing the bolt to the door and edges of the door engaging said guiding- 1 means for adjustably connecting said bolt grooves, a pivoted, radial arm above-the ceili with said arm.
